Calculate allowable percent wall <br /> or deadman displacement, 6p/D. 14 St& 16 St- Marina District <br /> 2. Use Curve A if resisting soil is new compacted structural fill. Port of Everett <br /> Use Curve B if resisting soil has not been replaced. Using the <br /> appropriate curve, determine the Mobilization Factor from the Everett, Washington <br /> graph above. MOBILIZED PASSIVE <br /> 3. Factor the ultimate passive earth pressure(PUNT)provided in our LATERAL EARTH PRESSURE VS. <br /> recommendations by the mobilization factor to obtain mobilized MOVEMENT <br /> passive earth pressure(PP)(e.g.for a mobilization factor at <br /> 60%, PP=0.6"`PULT).
